Methyl mercury concentrations in seafood collected from Zhoushan Islands, Zhejiang, China, and their potential health risk for the fishing community

Seafood is an important exposure route for mercury, especially methyl mercury (MeHg). Therefore, we quantified MeHg concentrations in 69 species of seafood including fish, crustaceans and mollusks collected from Zhoushan Islands, China. MeHg concentrations ranged from 1. The daily dietary intake and hazard quotient for MeHg were calculated to estimate exposure and health risk through seafood consumption by local inhabitants. The calculated HQ was lower than 1, thus indicating that the exposure was below the risk threshold of related chronic diseases. However, higher MeHg concentrations in fish species such as Scoliodon sorrakowah and Auxis thazard are concerning and may pose health risk through continuous consumption by local inhabitants.China Spark Program (2015GA700094); Medical Health Science Foundation Program of the Health Department of Zhejiang Province (2020RC137); Science and technology Program of Zhoushan City (2017C32089); Medical Health Science Foundation Program of the Health Department of Zhoushan City (2018G02)) and the Chinese Academy of Sciences Fellowships under the Chinese Academy of Sciences President's International Fellowship for Visiting Scientists (2018VCC0002).info:eu-repo/semantics/publishedVersio

Sorting Crabs: An Analysis of Tourism, Economy, Labor and State Division at Zhoushan Fish Market

This project focuses on three main topics and their “changes” in recent years. Chapter I focuses on the first topic, the relationship between the State of China and the State of Zhoushan, as well as the tension on fishing, tourism, and economic growth between these two states. Chapter II focuses on labor and class division at the Zhoushan fish market. Chapter III focuses on tourism and economy at ZhouShan. Fieldwork was conducted in two seasons: the first during the summer of 2017 at the Zhoushan fish market, and the second during the winter of 2017 at the Minsu in Zhoushan

Stocking, Enhancement, and Mariculture of Penaeus orientalis and Other Species in Shanghai and Zhejiang Provinces, China

China's marine aquaculture landings provide only 18% of its combined freshwater and amrine capture and culture landings, at a per-capita consumption of only 3.2 kg/yr out of a total of 18.1 kg/yr. We described development and some of the results of long-term mariculture and stocking/enhancement projects that have been underway for up to 20 years in the Hangzhou Bay area. Penaeus orientalis (also referred to as P. chinensis) stocking provided up to 400 t/yr, at a total cost-benefit ratio of up to 8 Yuan of landed shrimp per Yuan invested in shrimp stocking. Over 40 t of Penaeus orientalis were produced commercially in 1993, with proceeds being used to fund mariculture and fisheries research. Large scale edible jellyfish restocking is also underway, while semicommercial culture of abalone, Haliotis diversicolor, has been successful. Technical problems limitig mariculture have been solved successfully for some species

Characterization of severe fever with thrombocytopenia syndrome in rural regions of Zhejiang, China.

Severe fever with thrombocytopenia syndrome virus (SFTSV) infections have recently been found in rural regions of Zhejiang. A severe fever with thrombocytopenia syndrome (SFTS) surveillance and sero-epidemiological investigation was conducted in the districts with outbreaks. During the study period of 2011-2014, a total of 51 SFTSV infection cases were identified and the case fatality rate was 12% (6/51). Ninety two percent of the patients (47/51) were over 50 years of age, and 63% (32/51) of laboratory confirmed cases occurred from May to July. Nine percent (11/120) of the serum samples from local healthy people without symptoms were found to be positive for antibodies to the SFTS virus. SFTSV strains were isolated by culture using Vero, and the whole genomic sequences of two SFTSV strains (01 and Zhao) were sequenced and submitted to the GenBank. Homology analysis showed that the similarity of the target nucleocapsid gene from the SFTSV strains from different geographic areas was 94.2-100%. From the constructed phylogenetic tree, it was found that all the SFTSV strains diverged into two main clusters. Only the SFTSV strains from the Zhejiang (Daishan) region of China and the Yamaguchi, Miyazakj regions of Japan, were clustered into lineage II, consistent with both of these regions being isolated areas with similar geographic features. Two out of eight predicted linear B cell epitopes from the nucleocapsid protein showed mutations between the SFTSV strains of different clusters, but did not contribute to the binding ability of the specific SFTSV antibodies. This study confirmed that SFTSV has been circulating naturally and can cause a seasonal prevalence in Daishan, China. The results also suggest that the molecular characteristics of SFTSV are associated with the geographic region and all SFTSV strains can be divided into two genotypes

Study on the Foreign Publicity Translation of Marine Culture—Take Zhoushan for Example

The development of foreign publicity translation of marine culture is of great significance to the internationalization of Zhoushan Archipelago New Area. Based on Lasswell 5W mode (Harold Lasswell, 1948), this paper will combine some successful cases of foreign publicity translation of marine culture at home and abroad and analyze the present situation of foreign publicity translation of marine culture in Zhoushan Archipelago New Area by means of questionnaire surveys and the literature study on existing newspapers, periodicals and websites in Zhoushan. Accordingly, some suggestions are put forward to improve the deficiencies of the translation of marine culture in Zhoushan and innovate the ways in translating the marine culture, thus boosting the development of marine tourism economy and promoting the establishment of International Ecological Leisure Tourism Island (2016) in Zhoushan

How far can one go? : how distance matters in island development

Island development trajectories are heavily impacted by their relevance, similarity, complementarity and value in relation to continental development pathways. I would argue that this is so, also because of the physical proximity of islands to their respective metropolis, making the former island units in and of their respective mainland. This paper proposes a politics of distance. It examines how physical detachment from the mainland (and from central government) impacts on an island’s ability to determine its own destiny and developmental course. This paper does so by reviewing how near islands and remote islands have: (a) nurtured different levels of jurisdictional status and autonomy; and (b) used that jurisdictional resource, where available, to chart their own development trajectory, in ways that may be similar, complementary, different and outright in opposition to mainland ambitions and plans. In such liaisons, remote islands are more likely to avoid the clutches, overtures and demands of (more distant) powers—and thus depart from mainland agendas—than near islands.peer-reviewe

From a feeder port to a hub port: the evolution pathways, dynamics and perspectives of Ningbo-Zhoushan port (China)

This paper analyses the spatio-temporal evolution of Ningbo-Zhoushan port growing from a feeder port to a hub port finding the historical pathways followed by its expanding in terms of container throughput capacity and total traffic. The dynamic mechanism of evolution is the results of economic globalization, containerization and its natural endowments in channel and terminal depths. Analysis of the traffic evolution and its underlying dynamics suggest 3 periods in the development processes of container transport in Ningbo-Zhoushan: (1) adoption period (1986–2000) in which the main dynamics is the impact of the Chinese ‘Open Door policy’; (2) acceleration period (2001–2008) in which the dynamics is related of the mainland China's entry into the World Trade Organization; (3) peak growth period (2009-now) in which the dynamics is impacted by the anti-crisis strategy against the financial and economic crisis in 2008. We analyse the perspectives of Ningbo-Zhoushan port. ARIMA model is employed to forecast the container traffic in the coming future; about after 2026, the throughput in Ningbo-Zhoushan port would reach about 49 million TEU which would be approximately equal to that of Shanghai port. The resultant port development would exemplify a model of spatial distribution such as a multi-layered gateway hub. In the respect of growth potential, Ningbo-Zhoushan port possesses excellent coastline resource suitable for deep-water berthing, bonded port policy and free trade zone policy. Geographical position, service level, hinterland economic level and government will support its perspectives.Peer ReviewedPostprint (author's final draft

Rise of social network based seafood industrial cluster and rural community transformation in Zhoushan Islands of China

2021 Spring.Includes bibliographical references.This thesis reviews the historical, political, and cultural foundations for establishing seafood industrial clusters at Zhoushan Islands, explaining the organizational level management, operation, and regulatory strategies utilized by seafood factory owners to achieve their success. This thesis explores the general labor pattern, the surveillance and hierarchies in seafood factories at Zhoushan Islands, inequalities and social stratification in the nearby local rural community, and the invisible consequences of state-led industrialization and rural transformation policies in the Zhoushan industrial cluster. A theme running through this discussion is how factory owners utilize available political, social, and economic capital from the elite social networks to build their pathway to succeed in operating seafood business, countering barriers, and handling potential risks

World News

An August 2006 report by China’s Zhejiang Provincial Environmental Bureau (“ZPEB”) highlights continuing damage from petrochemical waste, heavy metals pollution, and overfishing to the Zhoushan fishery in the East China Sea. The Zhoushan fishery is among the largest in the East China Sea, and home to more than three hundred fish species, more than eighty shrimp and crab species, and more than 125 varieties of algae. The fishery accounts for ten percent of China’s total annual fish catches and fifty percent of total catches for the Zhe- jiang Province. The ZPEB study indicates that 81 percent of the 20,800 km2 Zhoushan fishery earned a category four pollution rating, with a highest pollution rating of five, up from 53 percent in 2000
